I have a white t-shirt that is about 25 years old hanging in my closet. My wife had each of my children dip their hand in some paint and then put it on the T-shirt. It has been washed several times and the colors and names stay fresh.
I can't wear the t-shirt any more, but it still brings a tear to my eye when I bring it out to look at it.
The shirt says, "We love Daddy." then they have their hand prints with their names written underneath. My wife used a paint brush to write their names under their hand prints.
Yes, we make a big deal out of Mother's Day and Father's day and birthdays. When my parents turned 75, Our family drove 1100 miles to surprise them and sing "Happy Birthday" to them on their door step. (They didn't know we were coming.)
Good luck to you and yours.
